Coss Marte, a former drug kingpin turned fitness CEO, will share his story at the iWerx co-working space on Sunday, Feb. 12.

Marte, who is the owner of ConBody, came up with the company’s business plan while he was in prison serving time as the ringleader of a multi-million dollar cocaine operation. His doctor informed him that he was grossly overweight and that it would eventually kill him. Marte put together a series of exercises he could do in his prison cell and shed 70 pounds within six months. He shared his system with other inmates and put together the plan for Conbody.

The company went on to win several major business pitch competitions such as Pitch for Good by TOM’s shoes and the YPO Shark Tank competition with Barbara Corcoran. The company currently has more than 10,000 clients.

Marte hired formerly incarcerated individuals to teach the fitness clients, mindful of the struggle that former inmates have when they are released.

Marte and ConBody have been featured on hundreds of news shows and major media outlets. He has also shared his story at prisons, conferences and TEDx in the U.S. and Hong Kong.

At the event at iWerx, Marte will be speaking to youth and entrepreneurs. The event is free, but registration is required. The doors will open at 2 p.m., and Marte will begin speaking at 2:30 p.m.
